Juan Mata looks dejected at Manchester United just two weeks after joining from Chelsea

It’s taken less than three weeks but already Juan Mata appears to have realised the error of his ways after quitting Chelsea for Manchester United.

The Spaniard watched his former side return to the top of the Premier League table this weekend, while his new club slipped to nine points behind fourth-placed Liverpool after conceding an injury-time equaliser at home to Fulham.

The result means United have won just one of the three matches played since Mata’s arrival at Old Trafford, with Chelsea having beaten both Manchester City and Newcastle in the same period.

And the very real possibility of missing out on not only the Champions League but also next season’s Europa League appears already to be dawning on Mata, who looked thoroughly deflated when the final whistle went at Old Trafford on Sunday night.
